Temperature sensor The collector has a built in sensor sleeve If there are two or more collectors mounted in series the sensor is to be inserted into the collector sleeve nearest the return flow back to the hot water store Optimal contact can be achieved between the manifold and sensor by way of smearing the sensor with heat paste prior to insertion An optional lightening protection device can be istalled to protect the sensor from over voltage Maintenance The collector and arrays must be checked periodi cally An annual close up inspection must be per formed to check for damage leaks contamination and tube failures a less solar isolation in you b solar collector is shaded from sunlight Low working performance from heat pipe solar collector e Incorrect instal lation angle Calculate correct collector size amp ad just accordingly or install additional heat source i e Gas boiler Where possible re move source of shade or relocate collector c Failed vacuum tube ba failed vac uum tube with d Poorly installed heat pipe Refit the heat pipe Apply heat paste to condenser surface Reposition collector to an angle 51 10 UK only Free standing planning prior to deciding Wind load on roofs can create suction forces on the solar collectors In order to minimize suction forces the mounting frame must be installed as follows The subsurface must be sufficiently sustainable and2. The collector field can be mounted at different angles according to individual applications For example larger systems used for heating support require a 60 degree angle in winter time to maximise solar gain this reduces the system efficiency in sum mer when the system is not required for heating Systems that require all year coverage such as hot water require 45 degree angle to maximise summer winter gain Systems that are predominantly used in summer are most efficient at 30 degree angle Install the profile rails in the in the pre drilled holes in the hypotenuse of the bracket insert the clamp and hanger brackets on the lower and upper profile rails mount the collector on the hanger brackets and clamp down each collector one at a time connecting the compression fittings to each collector as you install the next collector O mint renewables System Installation Schematics Steca Wiring Connections Pump connections Live Neutral Earth T1 T2 Position of the terminals Power connections Live Neutral Earth Refer to controller user manual for time date and system configuration set up g mint renewables Unvented thon with dur fine ff foo A E Fah Aral soler pump iaaa f ir EA Premurued orliafert hen cod 1 I T rt COM PRESSURED CYLIHDER Unvented Frk d r iver s re T n E AibA ci a Al f r HOT YWER I e More
